Overview

The IGS_PS_USEC_CAL_NUMS table is a core data structure within the Oracle E-Business Suite Student System (IGS) module. Its primary function is to act as a control table for managing the assignment of unique call numbers to unit section load calendar instances. In the context of academic administration, a load calendar defines the teaching periods and schedules for a course of study. This table ensures the integrity and uniqueness of call number assignments across different calendar types and sequences, which is critical for accurate scheduling, enrollment tracking, and resource allocation in higher education institutions running EBS 12.1.1 or 12.2.2.

Key Information Stored

The table's structure is designed to track the maximum call number used for specific calendar instances. Based on the provided metadata, the key columns include:

• UNIT_SECTION_CALL_NUMBER_ID: The primary key column, uniquely identifying each record in this control table.
• CALENDAR_TYPE: Part of a unique key constraint (IGS_PS_USEC_CAL_NUMS_UK), this column specifies the type of calendar (e.g., teaching, examination).
• CI_SEQUENCE_NUMBER: Also part of the unique key, this column holds the sequence number identifying a specific instance of the calendar type.

Together, the CALENDAR_TYPE and CI_SEQUENCE_NUMBER uniquely identify a load calendar instance for which the maximum assigned call number is being managed. The table likely contains an additional column (not explicitly named in the excerpt, but implied by the description) storing the actual maximum call number value.

Common Use Cases and Queries

This table is primarily accessed by transactional processes within the Student System to generate the next available call number for a new unit section within a given load calendar. A typical operational query would retrieve the current maximum value before incrementing it. For reporting and auditing purposes, administrators might query the table to analyze call number allocation patterns or identify gaps.

Sample Query Pattern:
To find the current maximum call number for a specific calendar instance, a query would join on CALENDAR_TYPE and CI_SEQUENCE_NUMBER. For troubleshooting, a DBA might check for constraint violations related to the primary or unique keys, which would indicate data corruption or a failed sequence generation process.

Related Objects

The table's relationships are defined by its key constraints. The primary key, IGS_PS_USEC_CAL_NUMS_PK, is based on the UNIT_SECTION_CALL_NUMBER_ID column. The unique key, IGS_PS_USEC_CAL_NUMS_UK, is based on CALENDAR_TYPE and CI_SEQUENCE_NUMBER. These keys are referenced by foreign key constraints in other tables within the IGS schema that store unit section details tied to specific load calendars. While the exact related table names are not provided in the excerpt, common related objects would likely include tables such as IGS_PS_UNIT_OFR_OPT (unit offering options) or IGS_PS_UNIT_SECT (unit sections), which would hold a foreign key to UNIT_SECTION_CALL_NUMBER_ID to link a section to its assigned call number sequence.
